Abstract: TREATMENT OF ULTRAHIGH MOLECULAR WEIGHT POLYOLEFIN         TO IMPROVE ADHESION TO A RESIN           ABSTRACT Method and apparatus for treating ultrahigh molecular weight, high strength polyolefin to improve its adhesive bonding to a resin such as epoxy, vinyl ester, polyester,  polyurethane, polyolefin or thermoplastic rubber are provided.  The method includes the steps of soaking the polyolefin in a first solution comprising (i) an aromatic ketone photosensitizer, and (ii) a first solvent selected from the group consisting of a benzene derivative, an alkyl halide, and a cyclic alkane; removing any excess first solvent; coating the surface of the polyolefin with a second solution comprising (i) about 15 to 70 weight percent of a monomer independently selected from the aforementioned group, (ii) about 0.25 to 5 weight percent of an aromatic ketone photosensitizer, and (iii) about 25 to 84.75 weight percent of a solvent selected from the group consisting of a low boiling point alcohol and a low boiling point ketone; exposing the coated polyolefin to a sufficient amount of irradiation to surface graft the monomer of the second solution to the polyolefin; washing the treated polyolefin; and drying for suitable packaging.  The apparatus features an irradiation treatment chamber through which the polyolefin is passed in a cooled tube for treatment.

Title: Removal of carbonyl impurities from a carbonylation process stream
Inventor: TORRENCE G PAULL
IPC: C07C53/12
Filed: 1991-11-18
Abstract: ABSTRACT         The methyl iodide recycle stream to a carbonylation reactor for carbonylating methanol or methyl acetate to acetic acid, acetic anhydride or both is treated to remove carbonyl impurities by reacting the methyl iodide stream with an aqueous amino compound which reacts with the carbonyls to form water soluble nitrogenous derivatives, separating an organic methyl iodide phase from an aqueous derivative phase and distilling the methyl iodide phase to remove heavier impurities.  The treatment of the methyl iodide recycle stream to the carbonylation reactor has been found to greatly reduce the carbonyls present in the product acetic acid or acetic anhydride and reduce tar formation in acetic anhydride and acetic acid-acetic anhydride co-production units.  The formation of nitrile from the nitrogenous derivative during distillation is minimized by adding water to the distillation column which washes the nitrogenous derivatives from the methyl iodide overhead.

Title: Combined multi-modal air conditioning apparatus and negative energy storage system
Inventor: USELTON ROBERT B
IPC: F25D16/00
Filed: 1992-01-03
Abstract: ABSTRACT OF THE DISCLOSURE   The present combined multi-modal apparatus involves: (a) apparatus for cooling, by means of a refrigerant circulating within coils disposed in a tank a negative heat energy storage material during a first time period; (b) associated apparatus for utilizing that stored negative heat energy during a second time period; and (e) most particularly, a tank by-pass structure for directly connecting a condensing unit and an evaporating unit during a third time period, such as for example when supplemental cooling is required. Specifically, the tank by-pass structure avoids circulation during the third time period of the refrigerant within the conduits or coils disposed within the negative heat energy storage material contained within the tank. Thus, during this third time period, heat is not imparted to the negative heat energy storage material by the circulating refrigerant, the cooled or frozen negative heat energy storage material is not heated or melted by circulating refrigerant, and thus does not have to be recooled or refrozen subsequently for re-storage of energy therewithin for later use in cooling during peak hours (i.e., during the second time period). During a fourth time period, the cooling Or both of second and third time periods is carried out simultaneously. Yet further, a heat pump may be operatively connected hereto for providing heat during a heating time period.
